2.2 Pixel-Array

The physical pixel-array is 360 x 292 pixels. The pixel size is 9.0µm by 8.25 µm. The useable image size for

NTSC format is 302 x 240 pixels while for PAL and CIF formats it is 352 x 288 pixels. An optional border 2

pixels deep on all 4 sides of the array can be enabled (Figure 2.3). The resulting image sizes are 306 x 244

for NTSC, and 356 x 292 pixels for PAL and CIF video modes.The border option is programmable through

the serial-interface.

Table 2.3 : Image Format Selection

Figure 2.2 shows how the 302 x 240 sub-array is aligned within the bigger 352 x 288 pixel-array.The position

of the 306 x 244 sub-array has been offset by one column, relative to central location. Image read-out is non-

interlaced raster scan. The larger 352 x 288 array covers pixels 4-355 and 2-289.

With extra border rows/columns enabled, and Figure 2.3 shows the relative array positions.

Note: To enable correct readout of sensor pixels, bit 7 of the Setup1 register [17] must be set to 0. Its default

power-up value is 1.
